Last week I did a reachy move to small undercling and first got it only with index fingerís first (distal) phalanx and only then grabbed it with the rest of the fingers. I felt something moved inside the index finger but ignored it, there was no sound heard. The finger got a little swollen in an hour but I felt no pain just stiffness. The next day morning the entire finger was swollen and I couldnít bend it all the way. After couple days of icing and NSAID application both pills and cream the swelling stopped. I still can bend it only half way and I found small bump on the top of the first joint (see picture). Any idea of the diagnosis? I will see a specialist for ultrasound examination but as it is summer it may take a while and I would like to start treatment as soon as possible. From what I found it may be A3 pulley partly or complete rupture. I immobilized the finger with tape but not sure what to do next.

Any advice will be highly appreciated.

Thank you

PS: I posted the same question at 8a.nu

I don't know what it is, but based on the photo, it's not a pully injury. Your pullies are on the other side of your finger, so it can't be that. Good luck, finger injuries suck.
